Abstract

Amaç: Bu çalışmanın amacı, bir Türk popülasyonunda
konik-ışınlı bilgisayarlı tomografi (KIBT) kullanılarak retromolar kanal (RMK)
ve retromolar foramen (RMF) oluşumunun değerlendirilmesidir.

Materyal ve Metod: Çalışmaya 350 hastanın (177 erkek, 173 kadın, ortalama
yaş 31.9, 18-70 yıl arasında değişen) KIBT görüntüleri dahil edildi. RMK,
mandibular kanaldan bağımsız olarak ramusta bulunan veya retromolar fossa
üzerinde bir foramen ile devamlılık gösteren ve mandibular kanaldan kaynak
alnan bir aksesuar kanal olarak tanımlandı. RMK'lar cinsiyet ve taraf dikkate
alınarak analiz edildi. İstatistiksel değerlendirmede, bağımsız örnekleri analiz
etmek için ki-kare testi kullanıldı. P <0.05 istatistiksel olarak anlamlı
kabul edildi.

Bulgular: RMK, hastaların% 11.42'sinde tespit edildi. Bunlardan
11'inde (% 3,14) bilateral, 29'unda unilateral RMK (% 8,28) saptandı. Sağ ve
sol taraflar arasında veya cinsiyetler arasında anlamlı bir istatistiksel fark
bulunmadı (P> 0.05).

Sonuç: RMK, oral cerrahi uygulayıcılarının bilmesi gereken
anatomik bir varyasyondur. Hasarlandığında hipoesteziye ve hastanın gereksiz
rahatsızlığına neden olabilir. KIBT, retromolar foramen ve kanalın anatomik
özelliklerini ortaya çıkarmak için yararlı bir araçtır.

Evaluation of the retromolar canal and foramina of the mandible with cone-beam computed tomography

Abstract

Background:
The goal of this
study was to investigate the occurrence of retromolar canal (RMC) and
retromolar foramen (RMF) using cone-beam computed tomography (CBCT) in a Turkish
subpopulation.

Methods:
This study
included high-resolution CBCT images from 177 male and 173 female, totally 350,
with average age of 31.9 years (18 to 70 years). The RMC was defined as an independent
accessory canal or arising from the mandibular canal continuous with a foramen
on the retromolar fossa. The RMCs were analyzed by considering sex and side. Independet
samples statistically analyzed with chi-square
test. P<0.05 was considered statistically significant.

Results:
The RMC was
detected in 11.42% of patients. Of these, 11 patients (3.14%) had  bilateral RMC, while 29 patients (8.28%) had
a unilateral RMC. There were no differences between left and right sides or
between genders (P>0.05).

Conclusions:
RMC is an anatomic
variation that performers of oral surgery should be aware of. It could
potentially cause hypoesthesia and unnecessary discomfort of patient when
injured. CBCT is a useful device to reveal anatomic features of the retromolar
foramen and canal.
